Cosmetics case having improved sealing properties

Abstract

The present invention relates to a cosmetics case, and more particularly it relates to a cosmetics case having improved sealing properties which, because of the improved sealing properties, can prevent the cosmetic core from becoming denatured by coming into contact with external air remaining in the cosmetics case and so is able to ensure good product quality even when used for a long time. To this end, the present invention comprises: a cosmetic core-mounting part; a raising and lowering member for raising and lowering the core which has been mounted on the core-mounting part; an idle-rotation drive member for making the core-mounting part and the raising and lowering member rotate idly; a core-protecting member which protects the core mounted on the core-mounting part, and which is connected to the idle-rotation drive member; a cap connected to the upper part of the core-protecting member; and a first sealing means disposed at the contacting surfaces of the core-mounting part of the core raising and lowering member and the fitting part of the core-protecting member.
